An article describing Dalton's atomic theory. Learn how this theory was the first attempt to describe a fundamental part of matter, atoms. Article also discusses where the theory is incorrect based on the knowledge we have today.

Article explores the key points of Dalton's atomic theory and the laws of conservation of mass and constant composition. Which points do we still use today?
